PLOW-BLADE.

Specification of Letters Patent.

Patented Oct. 27, 1914.

Original application filed November 24., 1913, Serial No. 802,775. Divided and this application filed March 17, 1914. SerialNc. 825,300.

To all whom it may concern:

Be it known that I, DEMETRIUS D. LITTLE- JOHN, a citizen of the United States, residing at Statesville, in the county of Iredell and State of North Carolina, have invented new and useful Improvements in Plow- Blades, of which the following is a specification.

This invention relates to plow blades, and it comprehends the provision of an improved device of the character stated which is designed, primarily, for use in connection with, or as a part of, a subsoil attachment, and which is so constructed that the point or blade proper may be applied to or removed from its carrier without ordinarily entailing rearrangement of other parts, and, when in place on the carrier, will have its tip or terminal disposed exactly in the line of draft.

An embodiment of the invention is illustrated in the accompanying drawing, whereof Figure l is a side elevation of a subsoil attachment equipped with the improved blade and applied to a plow, the latter appearing in dotted lines; Fig. 2 is a perspective View of the attachment; and Fig. 3 is a detail vertical section taken on line 33, Fig. 2.

The subsoil attachment, as represented, consists of two main parts or elements, namely: the ground-treating implement or blade 1 and its support 2. The latter element is preferably, though not. necessarily, of the type shown and described in my prior application, Serial Number 802,7 7 5, filed November 24:, 1913, of which the present case is a division, and since reference may be had to said application for a complete understanding of this element, extended explanation is omitted herefrom, it being considered sufficient for present purposes to state that it consists of front and rear bar-like members 2 and 2 arranged one behind the other and having their mutually-adjacent ends overlapped and adjustably connected together, to permit swinging movement of the rear member in a vertical plane. The front portion 2 of this compound bar is attached in some suitable manner to the plow beam 3, and, whereof the type just specified, conforms, substantially, to the shape of the downwardly-curved rear portion or neck of said beam directly against which it is arranged. The reartportion 2 of the bar is curved, as shown, for a purpose subsequently explained.

The ground-treating implement 1 preferably consists of a point or blade proper 1, and a carrier therefor composed of a base plate 1 and a face plate 1 the latter being arranged against the front of the said base plate and fastened thereto by bolts 1*. The plates 1 and 1 are formed with vertical centrally-located slots 1 and 1", and the first-named plate is also provided with a rearwardly-projecting web 1 that extends from end to end thereof and is arranged at one side of slot 1 The two slots 1. and 1 register and are of the same size, and that face of web 1 which is adjacent said slots is flush with the corresponding walls thereof. The rear terminal portion 2 of the supporting bar 2 projects through said slots and is fastened to said web by bolts or other suitable devices 1 the web being formed with a series of bolt holes to permit an adjustment of the ground-treating implement as a whole with respect to said bar, as will be understood from the drawing. The length of the face plate 1 is less than that of the base plate 1 and since the top edges of these two plates are arranged flush with each other, a space is left at the lower portion of the said plate 1 against which is arranged the upper portion 1 of the point 1, the combined length of this portion and of the plate 1 being equal to that of the plate 1 The aforesaid upper portion of the point is secured by bolts 1 or other fasteners to the plate 1 and these fasteners are preferably removable, thereby permitting the point to be detached and sharpened and, if necessary, replaced by a new point.

It will be observed from the foregoing that the slots in the carrier part of the ground-treating implement are arranged eX- actly central thereof, and that the tip or terminal of the point is in line with these slots, and, hence, is exactly in the line of draft. Also, the'point is itself readily detachable from the carrier, but, under ordinary circumstances, does not entail the removal of any other parts when sharpening of the point or substitution of one point for another is contemplated.

Having fully described my invention, I claim 1. The combination, with a support; of

a blade carrier embodying a plate formed of a blade carrier embodying juxtaposed,

with a vertical slot through which the rear end of said support projects, and with rearwardly-extending, vertical web located at one side of said slot and against which said support end is directly fastened; and a bladeJconnected to the lower portion of said carrier, i a

2. The combination, with a supporting bar having a downwardly-curved rear end; of a blade carrier embodying a plate formed v with a vertical slot through which the curved end of said bar projects, and with a rearwardly-extending, vertical web located at one side of said slot, said bar end extending downwardly along and being secured directly against said web; and a blade connected to the lower portion of said carrier;

3. The ombination, with a supporting bar having a downwardly-curvedrear end;

Copies of this patent may be obtained for connected, base and face plates formed with registering vertical slots through which the rear end of said bar projects, the base plate projecting below the face plate and having 25 a rearwardly-extending, vertical web formed upon its outer face at one side of the slot therein, against which web said bar end is directly fastened; and a point having its upper portion fastened to the projecting 30 lower portion of said base plate, with its upper edge flush against the lower edge of said face plate.

In testimony whereof I have hereunto set my hand in presence of two subscribing 'wit- 35 nesses.
